He had been keeping a close watch over the other party's actions while the poisoned wine was forced down his throat. From the very beginning, the other party had never touched the wine at all, coming into contact with the cup and gourd only. Considering the discreet poisoning method, there was no doubt that the other party was a poison master!
More importantly, the poison was so potent that even a Saint 1-dan pinnacle expert like him was rendered powerless. Without a doubt, the other party must be a 6-star poison master at the very minimum.
For a poison master of your caliber to not even know the location of the Poison Hall... Were you intentionally doing this to teach me a lesson?
It was laughable that he even tried to use poison against the other party... In the end, he ended up getting a taste of his own medicine...
